Specification of Letters Patent.

Application filed .Tune 14, 1918, Serial No. 240,017.

To all whom it may concern:

Be it known that I, JOSEPH VILARDO, a, citizen of the United States,residing at Buf falo, in the county of Erie and State of New York, haveinvented new and useful Improvements in Sash-Locks, of which the fol"-lowing is a specification. J

This invention relates to sash. looks and it consists in the novelfeatures hereinafter described and claimed.- 1

An object of the invention is to provide a sash locking device of simpleand durable structure, one which may be aeasilyand quickly manipulatedto secure the sash or release the same.

With this object in view thelock comprises a bolt slidably mounted inthe casing which holds the sash and adapted to engage in a socketprovided at the edge of the" sash. A spring is operativ'elyconnectedwith the said bolt for holding the same in a protracted positionwithrelation to the casing. A lever mechanism is mounted in the casing andis adapted to be manipulated to move the bolt to a retracted positionwhereby its ends will disengage the socket in the sash.

In the accompanying drawing Figure 1 is a cross sectional view through asash and window casing, showing my device applied,

Fig. 2, is a fragmentary front elevation.

As illustrated in the accompanylng drawprovided at its edge with aseries of notches or sockets 2. The sash 1 is mounted for movement in acasing 3 and in the usual manner.- A bolt 4 is s1idably mountedin thecasing 3 and its end portion is adapted to enter one of the notches 2when the sash is held at a locked position with relation to the casing.A spring 5 is housed within the casing 3 and one end of the said springis connected with the casing and the other end thereof avitl'i' the bolt1.

The spring 5 is under tension with a tendency to normally hold the endportion of the bolt 4 projected beyond'the edge of the casing 3 andtowardthe sash 1;

As clearly illustrated in Fig. 1 a pulley 6 is journaled within thecasing 3 and a lever 7 is fulcrumed within the casing. A flexible chain8 is connected at one end With. the bolt 4: and at its other end Withone.

claimed is connected with the lever,

end of the lever 7. The intermediate portion of the chain 8 is trainedaround the pulley 6. Consequently it will be seen that when the lever 7is swung the chain 8-is moved longitudinally whereby the bolt 4 iswithdrawn or moved to a retracted position with relation to the casing 3'and against the tension of the spring 5.

, A rod 9 is end with one end of the lever 7 and the said rod passesthrough the sides of the casing 3. A knob 10 is journaled on the rod 9and the said knob is provided at its side with a lug 11 adapted to entera recess l2'provided in the casing 1 whereby the said knob 10 and therod 9 nal movement.

When the knob 10 is turned upon the rod 9 so that the lug 11 is movedout of the recess 12 the knob and rod may be moved are held againstlongitudilongitudinally consequently means are pro-.

vided for swinging the lever 7. \Vhen the knob 10 is turned upon the rod9 so that the lug 11 enters the recess 12 the parts are locked againstthe movement just stated.

It is apparent that when the sash has been adjusted in the casing 3 thesashmay be held at the adjusted position by permitting the end of thebolt 4 to enter one of the notches 2. 'VVhenit is desired to move thesash this may be accomplished by manipulating the lever whereby the endof the bolt is withdrawn from the notch in the edge of the sash. 7

Having described the invention what is In combination with a sashmovably mounted in a casing, a sash lock comprising a bolt ,slidablymounted in the casing, a spring for normally holding the bolt inprojected position with relation to the easing, a lever fulcrumed in thecasing, a pulley journaled in the casing, a chain connected at one endwith the bolt and at its other end with the lever and having itsintermediate'portion trained around the pulley, a rod a knob journaledupon the rod and having a lug, the said casing having a recess adaptedto receive the said lug.

JOSEPH VILARDO.
